Abstract
A torque-limiting axle nut includes an inner nut having an inner-nut body forming a threaded center hole that defines a rotation axis. The inner nut also has a flange that encircles and extends radially away from the inner-nut body. The flange forms a plurality of recesses. The axle nut also includes a retaining ring encircling the inner-nut body and an outer nut encircling the inner-nut body. The outer nut forms grooves that extend axially upward from a bottom face of the outer nut and that extend azimuthally around the rotation axis. For each pair of neighboring grooves, the outer nut forms a ridge therebetween. The axle nut also includes a wave spring that encircles the inner-nut body and is located axially between the retaining ring and the outer nut. The axle nut also includes ball bearings seated in the recesses and extending into the grooves.
